Securock® ExoAir® 430 System – the only gypsum
sheathing panel integrated with a pre-applied fluid air-barrier
membrane. The panel brings two proven technologies
together – USG’s Securock Glass-Mat Sheathing and Tremco’s ExoAir
fluid-applied air barrier membrane into one panel that controls air,
water and vapor in a very efficient way. With document system
performance that goes beyond industry requirements, the
Securock® ExoAir® 430 System gives architects
the confidence to specify and building owners the performance they demand.
When installed with the approved detailing accessories and in
accordance with the Installation Instructions, the System is
classified as to fire resistance, NFPA compliant, ABAA approved and
listed with Progressive Engineering Inc.
The controlled factory application of the membrane to the face of
the panel provides the assurance that only a traditional thick-film
membrane can. With the Securock® ExoAir® 430
System, application variability of the air barrier is no longer a
concern; our controlled factory environment ensures proper mil
thickness and membrane uniformity, which means no more job site rework
and less job site waste. In addition, membrane adhesion is assured; it
can’t wash off from rain or from improper sheathing preparation. And
finally, the direct connection of the detailing sealants to the air
barrier membrane gives you the visual verification of air barrier continuity.
The Securock® ExoAir® 430 System is a full
system of products that have been tested for chemical compatibility to
make the critical connections of the entire building.
